ABSTRACT:
A device for the cyclic rearrangement of a pile of rectangular sheets, especially photographic prints. The device includes first and second frame parts (12, 14), of which one has a viewing window (35) in front of a principal face of the pile. The frame parts can be pulled away from each other and pushed back together again parallel to the plane of this face. A single sheet is removed from one end of the pile when the frame parts are pulled away from each other and returned to the other end of the pile when the frame parts are pushed together. During its movement relative to the window, the sheet facing the window is held spaced from the window by elements on the frame parts which are arranged and designed so that they overlap all edges of the picture but nevertheless render possible the passage of the picture through the gap defined by those elements.
